The Samix Serpent Cobra GT 3.0 Servo Deck Conversion was designed by former KM Racing H-K1 designer Hung Cheung Hang, to create a better balanced servo deck option. By moving eliminating the molded plastic servo tray assembly, and using a much smaller, vertically mounted receiver box, the Samix servo deck reduces weight and improves the weight balance of the chassis. It allows the use of 56x31x31mm and 86x29x15mm size receiver batteries, and when the smaller 56x31x31mm size is used it allows you two different mounting options for tuning the weight bias. Package includes all necessary hardware required to complete the conversion.
